Batch segment splitting

[Bearmancer]

I have a folder with several files that are each more than 20m. I want to run a single command that automatically splits them at the 20m mark. At the moment I have to do this for every file individually. Is this possible to automate?

See FAQ:

• Can LosslessCut do a batch conversion of multiple files?
  • Most likely not, but if you download FFmpeg on your computer and then ask an AI exactly what you want, it might be able to create a bash script for you. Example ChatGPT prompt: Can you help me write a bash script that for each .mp4 file in a specified folder, losslessly cuts off the first 10 seconds from each file? - You can also feed the AI commands from "Last FFmpeg commands" page in LosslessCut as an example.

Okay. I did it but it was slow as molasses the first time. It was quite fast the second time so issue solved. Thanks.
